Morrissey has cancelled his entire US tour, blaming a cold he caught from his support act Kristeen Young. However, Young has hit back and strongly denies that she is responsible.

Fansite True To You, which is regarded as a reliable source of Moz lore and news, says that 55-year-old Morrissey collapsed following a show at Boston Opera House and was rushed to Massachusetts General Hospital where doctors treated him for "acute fever".

Tour promoters are reported to have asked St Louis singer Kristeen Young to step down from the immediate upcoming shows.after she confessed to "horrendous cold" earlier on in the tour.

Instead she left the tour entirely and now claims that Morrissey's allegations are incorrect and denies that her poor health was the cause for her leaving the tour.

"I am very sorry that Morrissey is not feeling well," Young is said to have written in a Facebook post which has since been deleted and went on to say that she "will not tolerate" stories being propagated about her health. "This is really too much and bizarre."

The tour preceded the release of Morrissey's new solo album, World Peace is None of Your Business, which is due in July.
